Status: RESOLVED WORKSFORME

(Firefox :: Theme, defect)

Attachment: index.html

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/536.26.17 (KHTML, like Gecko) Version/6.0.2 Safari/536.26.17

Steps to reproduce:

I was attempting to learn to use HTML5 full screen mode.  I entered full screen mode with JavaScript with a persona enabled.



Actual results:

The mouse event coordinates were not lining up with the canvas element that I had full screen.  In full screen mode on OS X, I noticed that part of the window chrome was visible.  I was using the space - wonderful world persona, and after disabling the persona, the problem resolved and the chrome was no longer visible.  The window.innerHeight property was substantially lower than the screen size.


Expected results:

The element should have taken up the entire screen, it should have been located at 0, 0, and its size should have been the screen size.

I tried this with about 5 personas with the same result.

I was able to reproduce this. Without a theme enabled, full screen mode works as expected. With a theme enabled there are a few pixels of tabs visible at the top of full screen mode.

Not reproducible on Win 7, so likely issue specific to Mac versions.

We stopped calling the theme based "Personas" that name several years back, when they were also integrated into normal themes in Firefox.

Therefore bulk-closing Persona related bugs as they are no longer valid. If you are still having a potentially related issue in the latest version of Firefox, please take a look on our support site (https://support.mozilla.org) or file a new issue.
